Spinal infections can occur spontaneously or be secondary after primary spine surgery (postoperative). Postoperative infections may be more frequent in long-term surgeries, instrumented surgery and reoperations.
The overall risk of infection is 2% in primary surgery and may increase up to 4% in reoperations.
Spinal infections require a rapid and effective diagnosis identifying the germ to ensure a specific treatment that reduces the morbidity of this process.
